A thermal dye transfer assemblage comprising:

(a) a dye-donor element comprising a support having thereon a dye layer comprising a dye dispersed in a polymeric binder, the dye being a deprotonated cationic dye which is capable of being reprotonated to a cationic dye having a N-H group which is part of a conjugated system, and
(b) a dye-receiving element comprising a support having thereon a polymeric dye image-receiving layer, the dye-receiving element being in a superposed relationship with the dye-donor element so that the dye layer is in contact with the polymeric dye image-receiving layer, the polymeric dye image-receiving layer comprising a mixture of an organic polymeric or oligomeric acid which is capable of reprotonating the deprotonated cationic dye and a polymer having a Tg of less than 19C and having no or only slight acidity.
